Validate and regenerate all seed data from PokeDB

- Regenerate seed JSON for all 37 games with more complete PokeDB data
- Add category field to games.json (original/enhanced/remake/sequel/spinoff)
- Include all 1350 pokemon in pokemon.json with types and local sprites
- Build reverse index for PokeDB form lookups (types/sprites for evolutions)
- Move sprites to frontend/public/sprites, reference as /sprites/{id}.webp
- Truncate Sw/Sh den names to fit DB VARCHAR(100) limit
- Deduplicate route names and merge unnamed child areas into parent routes
- Populate 7 previously empty games (Sw/Sh, BDSP, PLA, Sc/Vi)
